Abstract
The silanes (CF3)2N·CH2·SiX3(X3= Me3, Cl3, or MeCl2) have been prepared by free-radical addition of the corresponding silanes to NN-bis(trifluoromethyl)vinylamine. The polymer [(CF3)2N·CH2CH2·Si·O1·5]n and cyclic and linear siloxane polymers [(CF3)2N·CH2·CH2·SiMe·O]n have been prepared and their thermal and hydrolytic stabilities compared with those of the model compounds (CF3)2N·CH2·CH2·SiMe3 and (CF3)2N·CH2·CH2·SiF3. NN-Bis (trifluoromethyl)-2-bromoethane did not react with magnesium or lithium to give the corresponding metal derivatives. The reaction between mercury(II) bis(trifluoromethyl)amide and iodomethyltrimethylsilane gave perfluoro-(2-azapropene), its dimer perfluoro-(4-methyl-2,4-diazapent-2-ene) and, unexpectedly, fluoromethyl-trimethylsilane, and ethylfluorodimethylsilane.Keywords
